Fitment Notes & Exceptions
  • When installing the Helix Plus cassette, as with any cassette, ethirteen recommends checking chain wear. If your chain shows 0.5% or more wear, you will significantly decrease the wear life of your new cassette. Installing a new chain with your new cluster is a much better and economical solution.
